ROLLER-MILL.

SPECIFICATION forming part of Letters Patent No. 394,814, dated December18, 1888.

Application filed March 31, 1888. Serial No. 269,112. (No model.)

T0 all whom t may eoncern:

Be it known that I, JOHN R. BEYNON, ot Vatertown, in the eounty ofJett'erson, and in the State ot \\"iseonsin, have iiivented eertain newand useful Improvements in Roller- Mills; and I do hereby declare thatthe following is a tull, clear, and exact description thereof.

My invention relates to roller-mills; and'it consists in eci-tainpeculiarities ot' construetion and combination of parts, to behereinafter described with reference to the accompanying drawings andsubsequently claimed, whereby the yieldingr roller in such mills may bereadilyY and evenly adjustml throughout its entire length. v

In the drawings, Figure I represents a side elevation, partly insection, ot' a portion ot a roller-mill havi ng' my invention appliedthereto; and Fig. 2 is an end view ot' the same, partly broken away andin section on line 2 2, Fig. l. Figs. 3, l, and 5, are detail views, thelatter being; a horizontal section taken on line 5 5 otI Fig. 3.'

Referring by letter to the drawings, A represents a portion ot' thetrame-work ot' a rollermill, B the stationary roller, and O theadjustable yielding` roller. The journal-boxes of the stationary rollerare eaeh provided with a screw-threaded socket or opening, D, thatreeeives the eorresponding'ly-shaped end ot' an adj listing-rod, E,thatis loose in an opening,` in the adjacent journal-box F ol' theadjustable yielding roller C, the movement ot' this latter roller beingllimited in a forward direction by means of a eollar, G, on eachadjusting-rod and in a rearward direction by a spiral spring, Il, thatsurrounds each ot' these adjusting-rods between the journal-box Fthereon and the rear portionvotthe tramework A, in which said rods havea bearing', I, as illustrated by Fig'.V l. Fast on the rear end of eachadjusting-rod E is a worm-wheel, J, that meshes with a worm, K, on aspindle, Il, the latter having' its bearings in a hanger or easing7 M,that is preferably made in two sections hinged tog'ether and tted on thehub of said worm-wheel. The easing serves to protect the worm-gear fromthe dust and dirt, and the sections comprising,l said casing are l heldin their elosed position by a pin, N, that l passes through ears O,depending from the l top et said sections, thehiuge beingl similarlyeonstruetcd and lettered.

The inner end oi each spindle IA lits into a socket, P, Vin the a`ljaeent end of a handle, Q, and set-screws R serve to rigidly connectthe spindles with said handle, the sockets in the latter beingl ofsulieient depth to permit an adj ust-ment to suit mills of dit'lerentwidths.

By turning;l the handle Q the wurm-gear connection .l K with the adjlisting-rods E is actuated to move the roller (l to or t'rom thestationary roller l5, and, as .both ends ot the former .roller are actedupon at the same time, the adjustment is equal thrtrug'hout its length.

As best illustrated by Figs. l and 5, I prefer to elongate the bearingsb for the wormspindles Il in order to better adapt my device to millsthat have the journal-boxes ot' the adj ust-able .yielding-roller Cscrew-threaded on the rods E and the journal-boxes for the stationaryroller B loose on said rod, this eenstruction being' just the reverseol' that shown by Fig'. l.

The advantage ot the construction just deseribed lies in the t'aet thatin ease any hard intrang'ible material should get between the rollers oneither side ot' the Center the handle Q and the worm-spindles connectedthereto would be t'ree to assume the same angle as the vdisplacedroller; or, in other words, would remain parallel with said roller,thereby preventing any bindingl ot" said worin-spindles or kinkingI ot'the adjusting-rods.

In order to better insure the parallel movementI ot' the yielding rollerand the adjusting mechanism, I pret'er to depress the sides ot thesections that compose the easings M as shown by Figs. Il and 5, so 'asto obtainpoints T, that have a' beari ne' on the worin-spindles L, tokeep the latter in line with the centers of the worm-wheels J, thedepressions lgradually recedingl from said bez'l-ring'points toward theends ot' said casing-s.`

known styles ot' roller-mills, but as the arrangement ot' the spri n forh olding the yieldstruction by which the adjustment is effected Mydevice is applicable to any ot' the welling roller in its adjustedposition and the con-' IOO are so varied I have shown only one style otmill for the purpose ol' illustrating the applieation of my deviee; andit will be understood that I do not limit myself to any partieulz'u.'roller-mill, nor the arrangement ot' deviees whereby the yielding rollertherein may be :uljusted to or .from the stationary roller, it beingobvious that in some mills where my worm-wheels take the plaees ot' thetensionnuts for the springs ll said worm-wheels neeessari ly move on theadjusting-rods E, instead of having a movement therewith when thepositive adjustment is el't'eeted. Furthermore, I do not wish to beunderstood as limiting myself to the worm-gear eonneetion between theadjusting-rods and spindles L, it being obvious that a bevel or othersuitable gear may be employed l'or the same mrpose.

Having thus t'ully deseribed my invention, what I elaim as new, anddesire to seeure by v Iletters latent, is-

1. In a rolleremill, the Combination, with the viehling roller and itsadjustingrods, ot' a wheel t'ast on eaeh adjusting rod, a hangersuspended from the hub ot` eaeh wheel and pro\f"ided with an elongatedbearing, and a handle journaled in the bearings and geared to saidwheels, substantially as set torth.

i. In a rollermill,the combination,with the yielding roller and itsadjustingrods, ol a wheel t'ast on eaeh adjustingrod, a hanger suspendedfrom thehub ol' eaeh wheel, opposing spindles jourlialed in the liangersand geared to said wheels, and a handle detachably eonneeted at its endsto the spindles, substantially as and lor the purpose set t'orth.

3. In a roller-mill, the eombii'iaiion, with the yielding roller and its.'Ldjliisting-rods, of a wheel fast on eaeh. adjusting-rod, a bearingsuspeiuled from the hub of each wheel, opposing` spindles journaled inthe bearings and geared to said wheels, and ahandle Connected to thespindles and adjustable in length, substantially as set forth.

'i-. In a roller-mill, the emnbination, with the yielding' roller andits adjusting-rods, oli' aV wheel arranged on eaeh :uljusting-rod, aeasing mzule in two seetions hinged together and ltted to the hub ot'eaeh wheel,a spindle journaled in eaeh easing and geareifl to the wheelineased thereby, and a handle uniting the opposing spindles,substantially as and for the purpose set forth.

5. In` a roller-mill, the eombiiiation, with the yiehling roller and itsadjustingrods, ol' a wheel arranged on eaeh ad justing-rod, a easing`itted 1o the hub ot eaehwheel and having its sides depressed to formopposing bearingpoints and its ends provided with elongated bearings, aspindle arranged. in the elongated bearings ot eaeh easing to impingeagainst said points, wherebyT the spindle is kept in line Vwith thecenter of the adjaeent wheel, a gear eonneetion established between saidspindle and wheel, and a handle uniting' the opposing spindle.substantially as set forth.

In testimony that I elaim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Tiseonsin, in thepresenee of two witnesses.
